IMPROVEMENT IN SPOUTS FOR COFFEE-POTS.

Specification forming part of Letters Patent No. 163,502, dated May 18,1875; application filed April 26, 1875.

To all whom it may concern:

Be it known that I, NATHANIEL S. MoFAR- LAND, of the city, county, andState of New York, have invented certain Improvements in SpoutsforCoffee-Pots and other Vessels; and I do hereby declare that thefollowing is afull, clear, and exact description of the same, referencebeing had to the accompanying drawing, which forms part of thisspecification.

My invention relates to a spout which is intended more especially forcofiee-pots, but which may be applied to other vessels.

The invention consists in a novel construction of the spout, whereby,when attached to a coffee-pot or other vessel, a chamber is formed inthe spout below the outlet from the body of the vessel, andcommunicating therewith by a channel, so that a quantity of liquid isalways contained in the chamber, and the escape of aroma from the vesselis prevented, whether the liquid in the vessel is above or below theoutlet.

In the accompanying drawing, Figure 1 is a vertical section of acoffee-pot with my improved spout attached. Fig. 2 is a rear view of thespout, detached. Fig. 3 is a vertical section, showing a modification ofthe invention.

A represents a coffee-pot of any suitable construction. B is theimproved spout, which may be made of any kind of metal or any suitablematerial. The portion 1) of the spout which is attached to the pot ismade considerably larger than the opening a in the pot with which itcommunicates, and is attached in such a position that the opening a isin the upper part of the portion 1), and the lower end of the spoutextends considerably below the lower edge of the opening a, and forms achamber,'O. From the top and sides of the chamber 0 a diaphragm, D,extends down into the chamber beyond the lower edge of the opening a,the edges of the diaphragm, except the lower edge, being attachedclosely to the sides of the chamber; or, if desired, the diaphragm maybe made in one piece with the spout. The space between the diaphragm Dand the side of the vessel below the outlet a constitutes a channel,connecting the chamber 0 and the body of the vessel.

WVhen the liquid in the pot or vessel A extends up higher than theopening a a portion of said liquid will always remain in the chamber C.When only a small quantity of coffee is in the pot, and it does notextend up as high as the opening a, a small quantity of water may bepoured down the spout sufficient to fill the chamber 0 as high as thelower edge of the opening. Thus the diaphragm D and chamber 0,containing the liquid, constitute a trap, which effectually prevents theescape of any of the aroma from the pot.

The spout thus constructed is applicable to tea-pots and other vesselsas well as to coffeepots.

The form of the spout may be varied to some extent without changing thenature of the invention, as shown; for example, in Fig. 3, whichillustrates, even better than Fig. 1, one of the principal advantages ofthe invention, viz., that the communication of the spout with the potmay, without any loss of aroma by escape through the spout, be made asnear as may be desired to the top of the pot, and enables the liquid tobe poured from the upper part, where it is clearest. The form of spoutshown in Fig. 1, however, allows the spout-connection to be made nearthe top of the pot.

What I claim as new, and desire to secure by Letters Patent, is

A spout constructed as herein described, so as to form, when attached toa vessel, a chamher, 0, below the outlet a, and a channel connectingsaid chamber with the body of the vessel, whereby said chamber isenabled to constantly hold a quantity of liquid, and thereby prevent theescape of aroma, whether the liquid in the body of the vessel standsabove or below the outlet a, substantially as set forth.
